Galvanized steel strip packing galvanized process for plating solution configuration requirements

Galvanized steel strip packing galvanized process for plating solution configuration requirements. Hot packing zinc plating steel strip plating solution configuration: weighing boric acid strain within the clean plating tank, add water to two-thirds of the total volume, stir until all melt, then add the weighing good zinc sulfate solid, stir until all melting, melting zinc sulfate can make the solution become dirty yellow liquid, after adding zinc powder ( 1g/L) Let stand for 30 min after violent mixing 30 min interim solution. The filtered solution should be transparent, if dirty, should first check the solution PH is too high, sulfuric acid, is used to adjust PH value of solution to the specified value. Add brightener, supplement water, stir well, try to plating, if still should look for zinc sulfate pollution and quality of boric acid, if configured solution PH value is less than 3. 0 is that there is something wrong with the quality of zinc sulfate.
